Janus 4540 SATA II-SCSI RAID Product Bundles

Description

These bundles include a Janus4540 SATA II-SCSI unit with choice of four drive sizes, five-year warranty, U320 SCSI HBA interface card, & a maintenance kit that contains a drive, a drive tray, a power supply, & fan. Memory upgrades and battery backup units are also available - please ask your RaidWeb representative for details.

The 2U Janus4540 features high availability hardware & firmware architecture which automatically detects bad array sectors & failing disk drives before array data is affected. Operating system independent & transparent with Windows, Linux, Novell, UNIX, or Mac based servers. On-line expansion allows the user to add drives to an existing array without interrupting operation. Available with a battery backup. Dual flash ROM onboard.

The Janus 4540 contains the following built-in functions:

• Disk Self Test automatically tests RAID hard drive health. DST performs write, servo analysis, & read scan tests; the test results are displayed on the LCD & Hyperterminal outputs.
• Disk Scrubbing uses idle time to test disks. If a sector is corrupted, DS regenerates data from other RAID member disks & writes it to an uncorrupted sector. DS prevents having multiple corrupted sectors in a single stripe, one of the main causes of data loss.
• Disk Cloning used with the SATA SMART function, determines the optimum time for the system to begin cloning a failing drive to a system hot spare disk. The cloned disk automatically takes over array function, eliminating degraded performance during rebuilds.

The Janus 4540 is the perfect solution for anyone who needs large amounts of data storage while maintaining high data transfer rate and compact rack space. Common applications for the Janus 4540 include digital archiving, data vault storage, company wide data backup, and more.
